what are the realistic boost levels for a rb25.. t3/t4 with 550s.. right now with the 370s and 12 psi.. its doesnt seem to be making that much power..

Have you checked your compression yet? that turbo adapter you made was awesome, I just can't fathom why checking your compression is such a daunting task!

Have you checked your A/F ratio's? What are you running for fuel managment? Didn't you get an apex pfc? You may just need to get the A/F and timming setup and then you should make some good power.

Yeah the PFC just comes with a basemap dude... you need to tune it to make power.

With a properly tuned motor 20psi should be ok. I would recommond a head gasket up grade and correctly size injectors and a tuned computer.

how much do you charge for your chiped computers for 550s?

Dont get that chipped ecu bullcrap, get a power fc and call it a day. And also if you get a power fc we wont make fun of you when you have to get your ecu rechipped when you have added some more mods
